I just started using TE for my hvac as well as plumbing. When I had an issue, I called and TE sent a tech out pretty expeditiously. Daniel Rockstroh who has experience with Carrier systems was excellent! My Carrier hvac system had an extremely hard to diagnose issue. Daniel took the time to trace the problem and get us back up and running correct. There was no "no I cant" or "its fixed" when it wasnt. Now that my system has been serviced, I have absolute confidence that our home will be cozy this winter, no worries here. Thank you TE and Daniel!
